IBM Research Proves Quantum Circuits Outperform LLMs on Two Problems
IBM Research published a paper on September 15, 2026, showing a theoretical separation between small quantum circuits and large language models for one functional and one sampling task. The 60-page paper, 'Separating quantum circuits from classical LLMs,' was posted on arXiv on August 4, 2026. The authors note the results are purely theoretical and do not imply practical advantage due to noisy quantum computers.
